CS2 Demo Analysis Kit vs SC2 Replay AI Coach

CS2 Demo Analysis Kit includes DAK Studio, a free desktop platform for analyzing Counter-Strike 2 demos locally. It links statistics to the source match, round and tick, with a 2D replay for inspection. The app runs on the user’s machine without an account, upload or server. Its modules cover replay, player profiles, duels and mechanics, utility and economy, tournaments, and coach preparation. The built-in exporter imports .dem files or cs2-demo-format v3 ZIPs and parses them on the computer. Windows and macOS downloads include a DMG, installer and portable ZIP options. The full Windows portable ZIP includes the Cologne Major 2026 event package and map data; the core ZIP contains runtime only. The runtime rejects v2 packages, which must be re-exported with cs2df. DAK Studio is AGPL-3.0-only, while ecosystem packages and the Python shell are MIT licensed. The analysis layer is also consumed by RivalHub and CS2 Insight Agent.

SC2 Replay AI Coach is a free browser-based site for parsing, viewing, and analyzing StarCraft II and Brood War replay files. It accepts .SC2Replay files for StarCraft II and .rep files for Brood War. Replay pages present economy timelines, army composition, battle records, build-order timelines, strategy classifications, and coaching notes. The automated post-game coach reads replay events, derives economy and combat metrics, compares openings with known build patterns, and adds notes tied to replay timestamps. Deterministic rules identify tactics including drops, cannon rushes, proxies, fast expansions, and one-base all-ins. Uploaded replays remain available through shareable URLs, with listed team coverage from 1v1 through 4v4. The tool requires no account or download and states no replay-count limit. Uploading is available in desktop browsers where local replay files are stored. Co-op replay visualization is supported, but ladder-coaching assumptions do not fully fit commander-specific units and mission objectives. Frame-perfect micro grading is limited because replay data contains events and sampled positions rather than a full coaching video.
